FURNACE ARRANGEMENT OF STEAM-ENGINES.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed innuary 27, 19064 Serial lie. 298,297-

To all whom it nmy concern.-

Be it known that l, EUGEN Karma, :1 subject of the, German Emperor, residing at Stuttgart, in the Kin donl of Wurtemberg, Empire of (h-r'i|m11y, l1ave invented certain new and usclul improvements in and (,(HP nected with the Furnace Arrangement of Steam-Engines, of which the following is a description, reference being had to the accompanying drawings, and t0 the ligurcs of reference marked thereon.

The object of this invention is to provide a steam-engine in which the steam is generated directly adjacent to the engiiie, the steam-generating chamber forming a jacket for the cylinder of the en ine.

A further object of are invention is to provide a steam-engine in which water in small quantities is vaporized as needed for the operation of the engine.

A still further object of the invention is to provide an engine and steam generator in which a finely-eomminuted or fluid fuel is admixed with air under compression and consumed as required for the generation of steam.

A still further object of the invention is to provide an automatic fuel-burner in which com ressed air is utilized for controlling the feeding of the fuel and also as a meansfor forcing the fuel into the combustion-cham- A still further object of the invention is to provide a device which embodies in small compass both a steam-engine and a. steamgenerator in which the generation of steam is started and stopped at will to control the operation of the engine.

in the accompanying drawings, Figure l is a side elevation of an engine and steam-generator constructed and arranged in accordance with the invention. Fig. 2 is a vertical sectional view of the same in a plane at a right angle to Fig. 1. Fig. 3 is a sectional plan view through the cap or cover of the device. Fig. 4 is a vertical section through the combustion-chamber and 'fuel-leeder; and F i 5 is a view similar to Fig. 4, drawn to an en arged scale.

Similar numerals of reference indicate correspondin parts throughout the specifi a- Lion and rawings.

The engine is mount-ed on a suitable base or support, including a cranlecasing 2, that has sultablc bearings for the support of the main shaft 27.

On top of the crank-case is secured a cylinder 8 and a cylinder-jacket 2 these being concentrically disposed and the space between them constituting a steameneratin chamber, the latter being open at t 10 top anil communicating with a steam-dome 3. The cylinder receives a trunkiston 25, connected by a rod 26 to the cran lc-shait, and steam from the dome is supplied to the cylinder through a suitable steam-chest 24, contain mg a valve for controlling the supply ol steam. The valve and the steam-chest, their parts and connections may be of any type in common use, these being too well known to re uire specific description he combustion-chamber is preferably formed ef'two castings 4 and 5 of which the cap member 4 extends throng "an openin in the lower wall of the steam-dome, an from this ca leads a fine 7, which is coiled helicaliy witiiin the jacket 2, and terminates in a discharge pipe or this 9, that leads from the bottom of the jacket. The products of combustion ass in a helical course through this flue on heat the water which enters at 10, the steam thus generated passing to the dome 3, and from thence to the steam-chest.

At one side offlthe combustion-chamber is a fuel-feeding chamber 16, to which pulverized or fluid fuel is fed through an inlet 20. From one side of the fuel'chamber leads a dischargeipe 12, the end of which is turned u at a right angle ahd has a bell-she ed dis- (la! a e-mouthin1mediatelyunderade5eeting- At one side of the fuel-chamber 16 is a cylinder 17, having a head or cap 18, and in tIlS cylinder is a. piston 15, carrying an airnozzle 13, the tapering discharge end of which is adapted to fit within the tapering end of the dischar e-pi e 12, forming when closed a valve whic 1 wil prevent the passa e of fuel to the combustion-chamber. 'i re nozzle is guided and supported by a tube 19, glint is carried by one wall of the fuel-cham- Leading into the cylinder is a pipe 28, which is in communication with an air-pump or other source of supply of air under pressure, and when air is admitted it acts upon and forces the piston 15 rearward against the action of a coiled compression-spring 29, i that is sealed in the rear end of the cylinder. This operation draws the nozzle 13 to the open position, and brings an opening 14 in the nozzle into communication with the front IlO end of the cylinder, so that a portion of the compressed air will flow throu h the nozzle and act as an injector to carry t 1e pulverized or fluid fuel from chamber 16 through the discharge or burner pipe 12. the jet of mmgled air and fuel stri ing against the dellector 11 and being more intimately combined and burned.

At the bottom of the combustion-chamber is an opening closed b a conical valve 6, which may be opened y a manually-operable lever 22, pivoted on a bracket 23, that depends from the wall of the combustionchamber. This valve carries a pin 21, on which an oil-saturated absorbent may be placed and i nited by a match or the like in starting the evice into operation.

The valve 6 may be opened in order to remove carbonaceous or other deposits when necessary.

Having thus described my invention, what I claim as new, and desire to secure by LettersPatent, is

1. In apparatus of the class described, the combination with a steam-engine, of a combustionchamber, a flue leadin therefrom, a steam-generating chamber om which steam is supplied to the engine, a deflector Within the combustion-chamber, a fuelchamber, a burner-pipe leadin therefrom and terminating short of the efiector, an

air-nozzle serving as a valve between the two chambers and provided with an opening near its rear end, a cylinder, a piston within the cylinder and connected to the nozzle, and means for admitting air under ressure to the cylinder to withdraw the nozz e to fuel-feeding position.

2. ln apparatus of the class described, a combustion-chamber, a deflector arranged therein, a fuel-chamber, a burner-pipe lead ing therefrom and terminating short of the deflector, an air-nozzle forming a valve for closing the burner-pipe, said nozzle having an openiw near its rear end, a cylinder, a piston within the cylinder and carr ing the nozzle, means for admitting air un er pressure to the cylinder to withdraw the nozzle to fuel-feeding position, and a spring tending to force said nozzle to closed position.

3. In apparatus of the class described, a combustion-chamber having a bottom 0pen ing, a valve normally closing said opening, and an absorbent carrier mounted on the valve, whereby preliminary heating of the chamber may be eflected.

In testimony whereof I allix my signature in presence of two witnesses.

EUGEN KLIMM.
